河西走廊韭菜种质资源调查

2003—2004年对河西走廊（祁连山北麓、中部走廊平原、北部荒漠地区）韭菜种质资源进行了调查，结果显示，南部祁连山区分布大量的野生韭菜，中部走廊平原栽培品种呈现多样性，北部荒漠地区分布有蒙古韭群落，阿尔金山东端没有发现野生韭菜。但由于过渡开垦、放牧，个别地区野生韭菜种质资源遭严重破坏，新品种的广泛推广，使得地方品种得不到有效保护。

The Germplasm Resource Investigation of Garlic in Hexi Corridor

From 2003 to 2004 we investigated the germplasm resource of garlics in Hexi corridor (North foot of QiLian Mountain, middle plain of the corridor, north inhabited area). The resoult of the investigation showed that a lot of wild garlics grow in mountain areas of south QiLian mountain. The cultivars are various in middle plain of the corridor .Mongolian garlic group are dispersed in northern vast desolate area. Wild garlic haven't found in eastern area of A Er Jin mountain. Because of serious reclamation, herding, wild germplasm resource of garlics are destroyed in some area. New species are wildly spread the local species are not effectively protected.
